Abstract

The procedure consists of assembling the primary components (11) and placing them in a furnace, subjecting to pre-baking and eliminating the binding agent of the anti-diffusion product. Then, without moving the components, the interior of the blade assembly (14) is subjected to a vacuum and a simultaneous increase in temperature to produce a permanent plastic deformation of the components. The interior of the blade assembly, made from a titanium alloy, is kept under the vacuum while an isostatic pressure is applied to the exterior, with the pressure and temperature conditions maintained to ensure a compaction of the anti-diffusion product and a pre-welding of the non-coated zones of the diffusion barrier. The assembly is subsequently inflated by gas pressure and superplastically moulded before subjecting to final machining.
